Anything android based will be affected. Any hardware targeted to run Android is going to become increasingly locked down and non-viable for people that want to customize.
The best option is to invest in libre hardware and open source software. If someone could come up with two or three-year-old flagship hardware that was unlocked. Which I could run, plasma touch, or some other similar Linux touch-based environment. I would be set.
I have an old 10 inch chrome tablet that I put post-market OS on. If all the hardware on it worked and it had more than four gigabytes of memory, the thing would be perfect.But even with all the flaws it currently has, it's still excellent.
